An information display is provided for displaying information with respect to the operation of the operating units. The operation display comprises polymer solar cells for providing an output signal based on a light radiation (R), where the signal is evaluated by an evaluation circuit for executing desired operating procedures in the vehicle.

Description

  • The The invention relates to a display and operating device in particular for vehicles. The operation of facilities in one Motor vehicle cockpit is often done via so-called interactive controls. An interactive control device includes an operating display on which one or more controls for vehicle facilities such as vehicle seats, windscreen wipers, window regulators, Navigation aids, etc., at least temporarily graphical representable are. The area of the (to the operating device belonging) operating display and the area of the (to the display device belonging) information display are on the same display. Through the information display can z. B. on the control panel desired Information is displayed. The division of the area sizes The two areas may be adapted to the current needs be adjusted. The entirety of the operation display and the information display is hereinafter referred to as display.
  • The Controls are associated with individual facilities of the vehicle. An action of a device is activated or triggered by having a user with an actuating element, in particular with a body part, such as a finger, the graphical representation of the control on the control panel touched. Interactive operating devices in which a Contact is necessary to trigger the operating action, are referred to as touch-screen controls.
  • The for the representation of the different operating elements available display area of the operating display is limited. To a variety of illustrated controls to operate only one operating element by means of a touch, Care is required on the part of a user due to the necessary concentration of the driver on the traffic not always given. Even when driving on a rough road it is often difficult for a user to do such a thing Perform operator action without errors during the journey. Therefore, it is desirable to have a user's intention to operate before a touch of the position-determining control element to capture and single or multiple of the controls shown, for the increased operating probability was determined, optimally scaled for one operation display. This requires the position of the actuating element, in particular a finger before to capture an actual act of action.
  • In order to measure the position of a body part (finger) contactless, is in the document WO 2004/078536 described a measuring principle for distance measuring sensors, are evaluated in the transmitted via a user high-frequency signals. Near the user's body is a radio frequency transmitter. In a motor vehicle, such a high-frequency transmitter is preferably integrated in a vehicle seat. The high-frequency signals coupled into the body of the user are capacitively received by the distance measuring sensors of the operating device. Based on a signal strength, the distance of a body part can be determined by the distance measuring sensor. On the basis of several such distance measuring sensors, which are arranged in a sensor arrangement, it is in principle possible to determine the position of the body part in front of the operating display by means of trigonometric calculation methods.
  • adversely With this known measuring principle it is that the transmission the high-frequency signals from the current state of the medium for the transmission of the signals is, here under the medium the whole of different sections existing connection between the radio-frequency transmitter and the radio-frequency receiver in the operating device is to be understood. Incidentally, is the known measuring principle not very easy to install, there individual units of the measuring system and their power supply in different components of the vehicle, such as dashboard, Vehicle seats, must be accommodated. Also can Reservations about the persons in the vehicle that radiofrequency signals pass over their body become.
  • The has display used in the display and operating device regularly an LCD display. Such a display has a number of disadvantages when used in vehicles. For one thing, the readability of the display is very different from the viewing angle dependent, so that when centered on the dashboard arranged Displays for each side of the display sitting Persons in the vehicle the display only in weakened Shape is visible. The LCD displays still need a direct or indirect backlight with a corresponding Warming, a corresponding energy consumption and a elaborate regulation of the backlight. Furthermore are Due to the technical conditions the LCD displays are stiff and This makes it difficult or impossible to do so more complicated shapes, for example on a dashboard of a vehicle, to adjust.
  • From the literature novel electro-optical display means are known which are based on the action of organic, light-emitting diodes (organic light emmitting diodes ~ OLED). Organic Light Emitting Diodes (OLEDs) are components of ultra-thin organic layers, similar to plastic films, that emit light when a voltage is applied. These components are not only very flat, but in principle can be produced over a large area and efficient in the generation of light. In addition, they respond very quickly to the applied voltage, are flexible and inexpensive to produce in large series. Displays with OLEDs require no backlight and allow low power consumption. You also have a wide viewing angle.
  • From the DE 10332953 A1 an OLED display has become known for mobile applications, wherein an additional operation by means of an operating device and this is integrated into the display. The operation is one or more responsive to touch input options, in particular, a touch-sensitive touch screen can be used, which generally has the disadvantages explained above.
  • The invention is therefore based on a display and control device of the type resulting from the preamble of the main claim and has set itself the task to provide such a display and control device with a responsive in a novel way to an approaching actuator control device. The object is achieved by the resulting from the characterizing part of the main claim feature combination. The invention consists in principle in the fact that the operating device recognizes the desired operation as a function of the incident on the solar cells light radiation. This is in contrast to the one from the DE 10332953 known arrangement that uses a touch screen and thus can not detect the approach of an actuator.
  • One Another important feature of the invention is that the Control device comprises polymeric solar cells. It has become demonstrated that the mode of operation of the known OLEDs are reversed leaves. In this case, instead of a Generation of light due to a voltage applied to the OLEDs Conversely, at the OLEDs pick up a voltage, if this with a Light radiation can be applied. As a result, this means that the OLEDs by a corresponding wiring also as on light responsive sensors can be operated, the following be referred to as polymeric solar cells.
  • Of the Effect of these as polymeric solar cells or organic solar cells designated OLEDs is known per se. The use of the polymeric Solar cells related to the operating device the generic display device offers significant benefits and a range of options
  • The in conjunction with a corresponding evaluation circuit itself approaching actuator discerning polymer Solar cells are located on a very thin foil. This film can also be adapted to very complicated surface shapes and thus offers against a usual LCD display significant advantages. The slide can continue including the solar cells containing them and the electrical connection technology transparent be executed so that this slide easily on the Surface of a displaying medium are attached can. Practically, this means that the film over the Surface of an operating display can be placed without the visibility of the displayed controls particularly would be influenced. The foil provided with the solar cells but can also be used advantageously in other technical fields For example, as a proximity switch or as a sensor on light responsive control circuit.
  • sets the film described with the solar cells over a Operation display, so there is another advantage. Because in this Case sensors and controls are superimposed, is the determination of the position of an actuator is more accurate, the more the actuator approaches the control. The probability that the actuator is a particular Trigger control element is therefore getting bigger. This can be exploited to a sufficiently large Probably the sensational the solar cells not only for the determination of the position of the actuator but also to exploit the triggering of the control itself, without that it would be necessary that the actuator actually touched the control. With others Words, if through appropriate measures, such as Measurement of the time as long as the actuator immediately above a certain operating element persists, it is ensured that the operation request is beyond doubt, so can over the sensory solar cells the corresponding control element be triggered immediately. On additional Measures such as a touch screen can thus be waived.
  • The position or the change in position of the actuator is detected without contact by the operating device by means of the measured by the solar cells light radiation or radiation change. This results in several methods, which are described below by way of example. These procedures are based on the consideration that invent According to the change in the incident on the solar cells light radiation on the position or movement of the actuator can be concluded. Since now the actuator itself is not an active radiator, a radiation source is needed whose light incident on the solar cell is dependent on the position of the actuator.
  • To the one can serve the brightness of the environment as a radiation source. It can by the operating device by the movement of the Actuator conditional shading of the solar cells incident ambient light are evaluated. Starting from the normal brightness of the solar cells detected by the solar cells Surroundings will be the, by the approaching actuator conditional, decreased brightness detected. In other words, by the operating device is the (by the approaching Actuator conditional) shadowing measured and thereby the Location or change in position of the actuator detected and thus the presumed confirmation request determined. The prerequisite is that a sufficiently large ambient brightness is available.
  • A another possibility for determining the presumed desire to operate Basically, this is the radiation of the display screen in particular use the operating display as a necessary radiation source. This is reflected by the reflection of the display emitted radiation through the actuator on the Activation request closed. The advantage of this measure lies in the fact that for such a measurement no ambient brightness is needed. The radiation of the operating display is preferred as a radiation source.
  • A Difficulty with regard to the last two measuring methods described This is because usually both the brightness of the environment as well as the display and control device with their OLEDs simultaneously act as radiation sources. Nevertheless, a meaningful knife result too Therefore, the size of the instantaneous radiation must be preserved the two radiation sources (without being influenced by the actuator) in the evaluation of the radiation received by the solar cells be taken into account. Regarding the brightness of the Environment this is not a major problem because the solar cells can be aligned so that they only measure radiation coming from the environment. So long no actuator in the immediate vicinity The solar cells measure only the brightness the environment.
  • There the brightness of the output by the display and control device Radiation can change constantly, are here additional measures necessary to a reasonable Measurement result of the solar cells to come. It can be considered be that the individual OLEDs of the display electrically controlled have to shine to light up. The prevailing control of the individual OLEDs allows sufficient conclusions on the brightness of the display and operating device as a radiation source too, so that the instantaneous brightness of these radiation sources in the evaluation of the measurement results of the solar cell consideration Can be found.
  • There the actuator according to the prerequisite the operation indicator may approach in the above considerations possibly the changing radiation of the Information display are neglected.
  • Around It is recommended to avoid the last mentioned difficulties in development of the invention, the application of the features of claim 2. The advantage of this measure is in particular that regardless of the operating and / or information display the display and the ambient brightness radiant additional Radiation source can be configured such that the radiation the environment and the ad are not taken into account got to. One way to do this, for example, is to the radiation of the additional radiation source in one to assign the solar cells associated frequency range in which the radiation the ad is ineffective. Furthermore, the radiation of this additional radiation source chosen so large be that the radiation from the environment and display is negligible. In this context, it is particularly advantageous if in training the invention find the features of claim 3 use. Because the additional radiation source in an invisible, in particular emits infrared light, she makes herself for the observer of the display is not disturbing noticeable. Furthermore, the solar cells can so on the radiation the additional radiation source are tuned that they are the visible radiation of other radiation sources not or only negligibly register. By the described strength of the invisible radiation as well as the possible spatial removal of the additional Radiation source from the information display is an additional Suppression of the radiation of the environment or of the display possible.
  • Preferably, the invisible radiating additional radiation source can be provided according to a combination of features according to claim 4 with correspondingly doped OLEDs. It is also advisable to use the image generation of the display or at least the operating display with Hil fe of OLEDs. This makes it possible to simplify the production method of the display and operating device according to the invention, since, for example, both the OLEDs of the display screen and the additional radiation source can be accommodated on the same film. This results in benefits
  • A such integration of the radiation source of the display and the additional Radiation source according to the features of claim 5 on the same slide can be configured differently.
  • A advantageous embodiment of this describes in development of Invention the combination of features according to claim 6. It is located the OLEDs of the invisible radiating additional radiation source although on the same slide as the OLEDs of the operator panel, but in a remote area. The advantage Such a measure consists essentially in that the image of the display by the additional radiation source is not disturbed, for example, in the picture of the Operator display non-indicating islands emerge from which radiates the additional radiation source.
  • At it can, as described, bring benefits, the additional Radiation source of the display device spatially settle. As far as the additional radiation source also like the Display for information and operation provided with OLEDs is, is recommended in a further development of the invention, the feature combination according to claim 7. The OLEDs of the additional Radiation source evenly between the OLEDs of the display, in particular the operating display be arranged. It is particularly advantageous that the im invisible light radiating OLEDs of the additional Radiation source does not disturb the image of the display on the display.
  • Preferably The polymer solar cells have a structure of the OLEDs of the operation display and / or the additional radiation source largely corresponding Construction. The main difference is only that of the Downstream electronic circuits supplied the OLEDs with voltage while tapping voltage from the solar cells becomes. This allows the production process of the invention Display and operating device simplify, since both the OLEDs Display displays (for operation and information) and / or the additional radiation source on the same slide can be accommodated as the polymeric solar cells. A Such integration brings a number of advantages. On the one hand can the OLEDs and the solar cells by means of the same Technology are produced, which leads to a certain simplification of the manufacturing process leads. Furthermore, the OLEDs and the solar cells are superimposed on a common or several arranged the flexible sheets, so that display device and Operating device even on complicated surface shapes can be arranged or applied to these. Furthermore creates with regard to the generic display and operating device the combination of OLEDs for the Display device and polymeric solar cells for the operating device Options for many advantageous developments that continue will be described below.
  • A Such integration of polymeric solar cells, the OLEDs of the display (i.e., information display and operation display) and / or the additional Radiation source according to the features of claim 8 on the same slide can be configured differently.
  • A advantageous embodiment of this describes in development of Invention the combination of features according to claim 9. Here are Although the polymeric solar cells on the same film as the OLEDs the display and / or the additional radiation source but in a remote area. The advantage such a measure consists essentially of that the image of the indicator is not through the polymeric solar cells is disturbed, for example, in the image of the display non-displaying islands in which the polymers are solar cells are arranged. By at the edges far from each other remote polymer solar cells of the operating device is also a more accurate determination of the position of the actuator possible.
  • At as described, it can bring benefits, the polymeric solar cells from the display and / or the additional radiation source spatially settle. As far as the polymeric solar cells also much like the OLEDs of the ad and / or the additional ones Radiation source constructed and only connected differently, recommends itself in development of the invention, the application of the combination of features according to claim 10. In this case, the polymeric solar cells the operating device evenly between the OLEDs of the display, in particular the operating display distributed be arranged. It is particularly advantageous that the polymeric Solar cells of the sensor device the image of the display device Do not disturb on the display.
  • In a further development of the invention, it may prove advantageous to apply the features of claim 11. It is assumed that not only the electrical wiring of the OLEDs but also the wiring of the polymer solar cells are made transparent can. Thus, an additional layer is placed over the layer of the display (particularly the operator panel) which receives the polymeric solar cells. In this case, the solar cells are preferably placed above the area of the operating display, which displays the operating elements on the display. Since the solar cells act directed and thus evaluate only radiation that hits from the environment on them, the operation of the solar cells is not affected by the radiation of the underlying display.
  • Farther It is also recommended according to the combination of features Claim 12, which adds to the additional invisible radiant Radiation source belonging OLEDs above the range the operating display on the display.
  • A particularly important and fundamental development of the invention results from using the features of claim 13, according to which the features of claim 11 and 12 are used in combination. After that are on one of the actual display Separate foil or layering both the OLEDs of the invisible radiating radiation source as well as the polymeric solar cells. In this film thus the entire sensor for the Recognition of the position or change in position of an actuating element to get integrated. Due to the recognition of a probable Actuation request of one or more on the operating display shown controls by means of a corresponding evaluation circuit These can then be scaled to their operations to facilitate. As already explained above but at corresponding probability of an actuation request the corresponding controls but also triggered directly without the need for a special touch screen would. Because the entire sensor system on a separate and transparent Film is housed, this can also be added later be retrofitted to an existing display, in the place appropriated the film on the mounted in display is, so for example on the operating display.
  • In The rule is the proximity of an actuator to the corresponding polymeric solar cells by modification of the light striking you. Another possibility, to the position or change in position of the actuating element determine results in the invention of the Feature combination according to claim 14. Thereafter, the operating device with a pulse generator, which the OLEDs of the additional Radiation source driven such that they pulsed and / or send out modulated infrared packets. The through the actuator reflected infrared packets become attenuated and with a transit time shift received by the solar cells. From the weakening of the infrared packets and / or the transit time shift then can the situation or the change in position of the actuating element by a corresponding evaluation circuit determine.
  • Increases the brightness of the environment on so is the picture on the display or the ad is less recognizable. In development of the invention recommends It is therefore according to the combination of features according to claim 15 also to use the solar cells in addition, to the brightness of the display on the display to the daylight adapt. The solar cells receiving the light of the environment thus serve not only to determine the position of the actuator but also to control the contrast of the display the brightness of the environment.
  • additionally can according to the combination of features according to claim 16 as training of Invention by the solar cells and the radiation of the display belonging to OLEDs. As is known, reduced At constant voltage, the radiation of the OLEDs over time. By applying the features of claim 16, it becomes possible the solar cells in addition to the regulation of the display exploit the voltage applied in the OLEDs.
  • There the solar cells only measure radiation in a defined direction can by special measures for it to ensure that from the solar cells the respective radiation to be measured can be specifically recorded. This can be done, for example, by that an adaptation of the display to the respective daylight gem. Claim 16 is only made if no actuator is detected. As the solar cells are usually aligned in this way are that they measure the light of the environment are some of the solar cells so polen and align that they (also) the radiation of the ad in order to use the characteristic combination Claim 17 to act. Since the brightness of the display screen or of the operation display according to the displayed images will fluctuate, is to ensure that through the solar cells the radiation of the display OLEDs at a standardized voltage is measured. Such a standardized voltage can the display device, for example when switching on the display and operating device are supplied.
  • One Embodiments of the invention will hereinafter be a Hand of the drawing shown.
  • The single figure shows a simplified representation of a z. T. broken shown disassembled display of a display and control device. The area of the display 1 is divided into an information display and an operating display 2 (both not shown in detail). The information display is used to display conditions (temperature, oil level, speed, mileage, etc.) of facilities in the vehicle but also to display information that may affect the environment of the vehicle (traffic situation, navigation maps and the like). The operating display is an input option for a downstream operating device, not shown in the figure. In this case, on the operating display graphical control elements such as buttons, buttons, slides are shown, which can be acted upon by an actuating element such as a finger. By pressing the controls, the desired information can be displayed on the information display.
  • The display, so both the information display and the operation display is provided with so-called OLEDs, which are composed of ultra-thin organic layers which emit light when a voltage is applied. The use of OLEDs displays for information display for mobile applications is from the DE 10332953 A1 known.
  • For the present invention, it is now important that the controls of the operating display by the actuator 3 can be applied without contact. This makes it possible for a correspondingly equipped display and control unit to recognize the probability with which a specific, on the operating display 2 illustrated control by the actuator 3 is controlled. The display and control device can then display the one or more control elements that are actuated with a high degree of probability and thus considerably facilitate the actuation of a control element. In order to make this possible, a sensor device, not shown, is necessary on a regular basis, which determines the position or change in position of the operating element by means of one or more sensors which approaches the operating elements so as to recognize the operating element which is most likely to be actuated by the user. This operating element can then be displayed scaled on the operating display and optionally touch-operated.
  • In order to determine the position or the movement of the actuating element serves an additional signal source, which emits a non-visible, in particular infrared radiation I. From this radiation I is a certain proportion of the actuator 3 reflected and the reflected radiation R is thrown back towards the operation display 2 , The reflected radiation is received by, in particular, not shown polymeric solar cells, which belong to an operating device, which forms part of the display and control device. The size of the reflected radiation R received by the individual solar cells is a measure of the distance of the actuating element 3 from the individual solar cells. Evaluate the distance of the actuator 3 of several solar cells, so you can change the position or bearing change of the actuator 3 in front of the operating display 2 to calculate.
  • The figure now shows one opposite the layering of the display 1 with their to the information display and the operation display 2 belonging to (not shown) OLEDs an additional layering 4 on the several rows of fields 5 are arranged, which represent transmitting / receiving units. Each of the fields 5 is preferably associated with a (not shown) operating element, which on the operating display 2 is shown. Each of the transceiver units 5 is equipped with one or more OLEDs, which emit the radiation I. The reflected radiation R is from polymeric solar cells in the fields 5 received, with each of the fields 5 has one or more of these solar cells. The likelihood of the actuator 3 a specific field and thus a specific operating element on the operating display 2 approaches, is for that control element on the largest associated transmitter / receiver units, the highest reflected radiation R and its solar cells thus deliver the highest voltage.
  • The stratification 4 represents a very thin foil in their fields 5 as a transmitter of the radiation I serving OLEDs and as a receiver of the reflected radiation R serving polymeric solar cells are applied. The transmitting OLEDs and the receiving solar cells are largely identical, with the difference that a voltage is applied to the OLEDs while a voltage is tapped by the solar cells. The foil 4 , the fields 5 and, which here too necessary electrical wiring are transparent, so that thereby the consideration of the on the operation display 2 visible controls is not affected. For better understanding, the operating display 2 and the foil 4 drawn apart from each other. In practice, the two components immediately adjacent to each other and mechanically formed a flexible unit that can be well applied to complicated shaped carrier.
  • The invention can be briefly summarized as follows. The object of the Er It should make it possible for an object, for. As a finger to be detected in front of a performing medium such as a display. The previously proposed sensor is mounted on the edge of the display and brings problems in the evaluation with it. Transparent OLEDs (Organic Light Emitting Diodes) offer new solutions. There are both transparent OLEDs that can emit light and OLEDs that are connected as a solar cell. These two in combination are to form a transmitter-receiver pair, which is mainly the sensing of performing surfaces (in this case in front of a display) to enable.
  • Through the use of infrared OLEDs as transmitter and receiver, a sensing can take place directly in front of the display without affecting the quality of the display. In an additional transparent layer immediately in front of the display, a transmitting and receiving OLED is applied. The OLEDs operate in the infrared range, so that the display of the display located behind it (display) remains visible. If the transmit OLED sends out its signal, this is sent by an actuator 3 reflected in range and falls back to the transparent layer. As a result, a certain part of the emitted radiation is detected in the presence of an actuating element on the receiving OLED. An evaluation electronics, not shown, determines whether the received radiation was reflected by background effects or by an object in front of the display with the transparent layer.
  • It is suggested before the display 1 an array 5 of transmit and receive OLED attach to simultaneously realize a position determination. The receiver with the highest received power is perpendicular to the actuator 3 , Also, a plurality of actuating element can be detected and the contour of the actuating element can be determined.
